GEORGE x. WOOD, OE MORRisrOwNV NEw JERsEY.

IMPROVED REFRlGERATlNG-CAR.

Specification forming part of Letters Patent No. 76,285, dated March 31,1868.

To all whom' it may concern:

Be it known vthat I, GEORGE K. WOOD, ot Morristown, in the county ofMorris and State of New Jersey, have invented a new and ImprovedRefrigerator-Gar; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

This invention relates to a new andimproved construction of arefrigerator-oar, as hereinafter fully shown and described, whereby theinterior of the oar may be kept at a low temperature and in a dry state,with conditions which insure the keeping of edibles, more especiallymeat, in perfect state of preservation for a long period of time.

The invention further relates to a novelty in the construction of thecar, whereby provisions at different stations on the route may be placedin the car without allowing the external air to come in contact withprovisions previously placed in it. Y

In the accompanying sheets of drawings, Figure l is a longitudinalvertical section of my invention, taken in the line w Fig. 2; Fig. 2, atransverse vertical section of the same, taken in the line y y, Fig. l.

Similar letters of reference indicate corresponding parts.

A represents the body of the car, which is double-walled, the spacebetween the two walls a a, being filled with a suitable non-conductingmaterial b. The top and bottom of the car are constructed precisely likethe sides, the top having a hinged portion, to serve as a lid, B.

Within the body A there is inserted a chamber, C, the sides and top andbottom of which (designated by o) are constructed of metal; and l) is asmaller chamber, also inserted within the body A, and constructedprecisely like (l. These chambers, of which there may be two or more,have each a separate door, d, -and a space, e, is allowed between thechambers, as well as all around between them and the inner wall a ofthebody A, at the top and bottom as well as at the sides, as shown clearlyin Fig. l.

The top of the chamber. C is slightly depressed to form a basin, E, toreceive the water from the ice, the latter resting on a grate, j', overthe basin, the space between the basin and inner double wall being made,by means of an arch, sufficiently ample to form an ice-l chamber.

The water is discharged from the basin E through a pipe, F, the lowerend of which is bent upward, as shown at g, Fig. 2, to form a seal tocut off the external atmosphere from the basin E.

The object in having a plurality of chambers is to admit of provisionsbeing put into the car at different stations on a route without allowingthe external air to come in direct contact with provisions previouslytaken in. For instance, if the main chamber G be filled at the stationfrom whence the car starts, it will not be opened before the car reachesits point of destination, the chamber D being opened to receiveadditional freight.

I would remark that the doors d d should be made with double walls,backed in any suitable manner, and made to t tightly when closed, so asto avoid the ingress of external air.

In the chamber C there is placed a series of upright hollow pillars, HX,which communicate at top and bottom with the dead-air space e. Thesepillars have hooks attached for the purpose of suspending meat to them.Similar hooks are attached to the sides.

The object of this arrangement is to have the meat or other provisionsthus suspended in contact witha cool surface and cool air; and, besidesthis, it admits of a large number of carcasses of meat being suspendedin the chamber without being crowded together, as would frequently bethe case were no provision made to suspend them anywhere rather than tothe metallic sides of the chamber C.

The smaller chamber D may also be provided with similar pillars HX, forthe same purpose.

I claim as ynew and desire to4 secure by Letters Patent- The pillars HX,arranged or placed within the provision-chambers, any or all of themcommunicating above and below the dead-air .space between said chambersand the sides ot' the oar, substantially as and for the purpose setforth.

The above specification of my invention signed by me this 21st day ofNovember,

GEO. K. wOOD.
